SVN全量备份+增量备份脚本

一、全量备份

环境：一台主SVN，一台备SVN（主要提供备份功能），后续可通过钩子脚本进行实时备份，后续发给大家。

工作原理：通过svn的hotcopy命令过行热备份，并进行一系列的检查，备份后通过rsync推送到备份机上。

脚本如下：

二、增量备份

环境：一台主SVN，一台备SVN（主要提供备份功能），后续可通过钩子脚本进行实时备份，后续发给大家。

工作原理：

1、备机上通过nfs挂载到主机上，主要实现通过svnlook youngest来查看主和备间各版本库的版本号差别。（挂载后相当于在本地一样，就可以使用youngest参数或取到主和备版本号的区别别，并进行打包。）

2、挂载并打包后，将打包后的文件存放到挂载目录中，在到备机上通过还原脚本分别对更新的版本库进行还原，并将结果通过邮件发给告知人。

脚本如下：
